The International Space Station's sterile conditions deprive astronauts of the opportunity to strengthen their immune systems through microbial exposure. To address this problem, future missions may use probiotic-based cleaners and foster diverse microbes in space habitats.

Visitors of the International Space Station are trained in English and Russian

Different space agencies develop different modules of the ISS, meaning their controls, documentation, and instrumentation are not always written in English. Because the first modules were delivered using US and Russian spacecraft, astronauts have been historically trained in both languages.

Visualize the impact of satellites and space debris orbiting Earth

According to NASA, approximately 9,000 metric tons of debris are orbiting Earth, with 70% of it located in low Earth orbit, where the Hubble Space Telescope and the International Space Station reside. The growing reliance on space-based platforms for modern technologies, including Starlink satellites, increases the risk of debris collisions.

Gravity assists are crucial for space travel beyond Mars

By traveling near a moving celestial object, a passing object can gain or lose speed and change direction due to the acceleration provided by their mutual gravity. Some missions are planned around spacecraft performing multiple assists, or slingshots, to reduce fuel requirements for long-distance travel.

A prototype greenhouse for Biosphere 2 is now part of a test habitat for Mars

The Space Analog for the Moon and Mars combines the Test Module greenhouse with a workshop, kitchen, common area, sleeping quarters, and a yard that mimics lunar and Martian surfaces.
